PURPOSE: To evaluate whether the outcomes and characteristics of a first IVF/ICSI cycle are associated with embryological and clinical outcomes in a subsequent cycle performed within 2 years. METHODS: This retrospective single-center obser…

PURPOSE: To evaluate whether artificial endometrial preparation using hormone replacement therapy (HRT) influences clinical and neonatal outcomes compared with modified natural cycles (mNC) in single euploid vitrified-warmed blastocyst tran…

AIMS: To evaluate DuoStim strategy across a decade from its clinical implementation in IVF by comparing embryological and clinical outcomes between the first and second ovarian stimulations (1st-OS and 2nd-OS) conducted within 30 days, focu…

OBJECTIVE: To examine the association between semen parameters, assessed according to World Health Organization (WHO)-2021 criteria, and paternal body mass index (BMI) and age, with embryological and clinical outcomes in ICSI cycles involvi…

All analyses were conducted using RevMan 5.4 and R.Sensitivity analysis Meta-analysis was performed using a random-effects model to account for interstudy variability.Heterogeneity was assessed with the I statistic.For each comparison group…

Objective: To provide a rigorous, multidisciplinary synthesis of the epidemiological, genetic, immunological, and environmental factors contributing to Premature Ovarian Failure (POF), with particular attention to regional disparities, occu…

BACKGROUND: Infertility affects around 17.5% of reproductive-aged individuals worldwide, posing significant personal and public health challenges. Although Medically Assisted Reproduction and Assisted Reproductive Technology (ART; e.g., in …

BACKGROUND: Endometriosis is a persistent inflammatory condition that affects women of reproductive age and causes pelvic pain. Chronic pelvic pain is a chronic regional pain syndrome involving the pelvic area. OBJECTIVES: This survey aime…

Unhealthy behaviors may contribute to the development and the progression of chronic diseases with negative consequences on patients' quality of life. The present study aimed to investigate the relationship between unhealthy behaviors (phys…

PURPOSE: An impact of different gonadotrophins selection for ovarian stimulation (OS) on oocyte competence has yet to be defined. In this study, we asked whether an association exists between OS protocol and euploid blastocyst rate (EBR) pe…

(1) Background: endometriosis is included in the list of chronic and disabling pathologies. This study aimed to examine patients' points of view about the quality of care for endometriosis during the COVID-19 pandemic; (2) Methods: we condu…

Progesterone is the ovarian steroid produced by the granulosa cells of follicles after the LH peak at mid-cycle. Its role is to sustain embryo endometrial implantation and ongoing pregnancy. Other biological effects of progesterone may exer…

Objective: To estimate the rate of intra-operative and postoperative complications, and to define the risk of 30-day major postoperative complications (Clavien-Dindo > 2) according to the presence of one of 10 different variables of minimal…

PURPOSE: Our primary objective was to assess whether immediately undergoing a second stimulation in the same ovarian cycle (DuoStim) for advanced-maternal-age and/or poor-ovarian-reserve (AMA/POR) patients obtaining ≤ 3 blastocysts for prei…

Endometriosis is a disease distinguished by the presence of endometrial tissue outside the uterine cavity with intralesional recurrent bleeding and resulting fibrosis. The most common locations for endometriosis are the ovaries, pelvic peri…

OBJECTIVE: To verify whether the capability of magnetic resonance imaging (MRI) in diagnosing deep infiltrating colorectal endometriosis (DICE) is improved using an association of MRI findings. METHODS AND MATERIALS: The imaging database o…

OBJECTIVE: To identify a possible marker of follicular depletion in relation to some histologic parameters of endometriotic cysts. DESIGN: Prospective study. SETTING: Università Cattolica del Sacro Cuore, Operative Division of Endocrinolo…

Conclusions:The size of the 2 -5 mm follicle pool is an independent and important contributor to the FA of PCOS.This result could be explained by an exaggerated physiological inhibitory effect from this pool on the terminal follicle growth,…
